When the trailer is below the surface at a boat ramp, upright guide-on posts provide a visible reference for reversing and loading. C.E. Smith's 40-inch and 60-inch sets use different support lengths. Compare height, adjustment and frame dimensions before choosing a replacement.

All three models are sold as pairs with mounting hardware and fit standard trailer frames up to 3 inches wide by 4-1/4 inches high. The PVC tubes have a 2-3/8-inch actual outside diameter.

MPN Assembled height Post colour Adjustment per side PVC sleeve Steel upright
27620 40 in White PVC 13 in per side 31-1/2-in white PVC sleeve 18-in vertical steel upright
27626 40 in Black PVC 13 in per side 31-1/2-in black PVC sleeve 18-in vertical steel upright
27640 60 in White PVC 19 in per side 47-1/2-in white PVC sleeve 39-in vertical steel upright
Post height means inches. The 40-inch and 60-inch model names describe height above the trailer frame, not a length in feet. These are unlighted post guide-on kits; trailer lights remain a separate requirement.

Check these measurements before buying

  • Waterline and height: 40-inch sets are lower; the 27640 stands 60 inches above the frame.
  • Frame crossmember: compare its width and height with the 3-inch by 4-1/4-inch standard mounting limit. A longer U-bolt kit is a separate solution for some larger frames, not part of the standard kit.
  • Adjustment range: the 40-inch sets adjust outward to 13 inches per side; the 60-inch version adjusts to 19 inches per side.
  • Position: the posts should be near the rear of the trailer, while still allowing the widest part of the boat to pass through them.
  • Replacement parts: 27620 uses white sleeve 11339; 27626 uses black sleeve 11329; 27640 uses white sleeve 11340. Uprights differ between the 40-inch and 60-inch versions.
